T0 @ZZ whom it puny concer-71,.-

Be it known that we, JOHN R. PARKS and JAMES H. DAY, citizens of theUnited States, residing at l/Vood Lake, in the county of Cherry andState of Nebraska, have invented certain new and useful Improvements inDraft-Equalizers, of which the following is a specification.

This invention embodies an improved draft-equalizer, and the mainfeature of the invention is comprised in the general simplicity of theconstruction of the device and the peculiar arrangement of the partscomprising the same, whereby special advantages arise in the practicaluse thereof.

For a full description of the invention and the merits thereof and alsoto acquire a knowledge of the details of construction of the means foreffecting the result reference is to behad to the following descriptionand accompanying drawings, in whichh Figure 1 is a top plan view of adraft-equalizer embodying the invention. Fig. 2 is a front elevation.

Corresponding and like parts are referred to in the followingdescription and indicated in both the views of the drawings by the samereference characters.

Referring to the drawings, the numeral 1 designates the tongue, and thenumeral 2 indicates a transverse equalizing-lever which is pivoted at apoint between its ends, as shown at 3, to said tongue `1. The eualizing-lever 2 is pivotally connected to Jthe tongue by means of aclip 4 or similar part attached to the same, said lever 2 being arrangedbeneath the tongue to admit of the use of the invention onmowing-machines. `The point of pivotal connection of the lever 2 withthe tongue 1 is nearer one end of the lever than the other. A doubletree5 is connected by a link 6a with one of the outer ends of the lever2that end which is more remote from the tongue 1. It is designed thatthe equalizer be of the three-horse type, and a short lever 6 isconnected at a point between its ends, as shown at 7, with a link S,which in turn is connected with the short end portion of the lever 2.The link 8 is pivotallypconnected with the parts 2 and 6, and the lever6 is pivoted at its inner end to a bracket 9, attached to the tongue 1,a swingletree 10 being connected to the outer end of the short lever 6by means of a link 11. The bracket 9 is of a peculiar form, being soattached tothe tongue 1 as to place the draft below the same, or, inother words, the disposition of the bracket 9 is such that the parts 6and 10 with adjacent connections are arranged below the plane of thetongue 1 and in the plane in which the equaliZing-lever 2 is located.The bracket 9 is composed of superposed bracket-irons, (indicated at 9aand 91),) said irons being of approXimately U form in top plan view. Thecurved ends of the irons 9a and 9b are disposed above and below,respectively, the end of the short lever 6, to which they are pivotallyconnected. Each of the irons 9a and 9b is formed at its spacedextremities with upwardly-projecting extensions 12, and these extensionsare connected together by means of U-shaped clamps 13. The clamps 13receive the tongue 1, and the ends of the clamps pass through theextensions 12 of the bracketirons above described, suitable nuts beingscrewed on the ends of said clamps to hold the same in securedpositions, The clamps 13 not only connect the bracket-irons 92L and 9btogether, but said clamps also secure the bracket-iron to the tongue.

The manner of attaching the bracket-irons has particular advantage inthat the bracket is arranged below the plane of the tongue, and,further, the attaching means by which the bracket is held in place doesnot weaken the tongue at all, as the clamps 13 do not necessitate theprovision of openings or the like such as ordinarily provided insecuring the parts of equalizing devices of this class.

The advantages of the invention will be obvious from the foregoing, andthe same are therefore not speciically set forth.

Having thus described the invention, what is claimed as new is- In adraft-equalizer, the combination of a tongue, a transverseequalizing-lever pivoted at its ends to the tongue, a bracket projectinglaterally from the tongue in advance of the equaliZing-lever, saidbracket being composed of upper and lower U-shaped bracketirons,U-shaped clamps receiving the tongue and connecting the bracket-ironstogether and securing the same to the tongue, a short lever connected atits inner end with the IOO bracket and having said end received be- Intestimony whereof We affix our signete tween the bracket irons, a linkconnecting tures n presence of tWo Witnesses.
